Question: How long after Zithromax 1000 mg is chlamydia contagious. If oral sex is done on me after 4 days would my friend be at risk of getting it orally ? Vinson was worn for intercourse. Thanks.
That was supposed to say condom not Vinson. Just FYI.

Brief Answer:
After 7 days of antibiotic chlamydia no longer transmitting

Detailed Answer:
Hi,

Oral sex can transmit chlamydia from infected person to non infected.
Similarly it takes a week post treatment for chlamydia to stop transmitting. That means 1000mg of zithromax would kill chlamydia numbers to a level less than inoculation level.
So I suggest not to participate in the intercourse for another 3 days.
